When you write, what is the difference between writing a paper and writing a discussion post?

Writing a paper is you simply telling people what you believe or think, giving or stating your position or where you stand on a particular subject matter while writing a discussion post is you sharing your opinion or believes with other people and requesting or seeking for their own opinion or believe back in return.

Hopefully this helps you, have a great day and never give up
